Check your User's Manual or the nameplate on the back of the alarm. Different smoke detectors & CO alarms use different kinds of batteries - 9V, AA, AAA - it all depends on the particular model you have. Use quality batteries like lithium batteries - having plenty of power is worth any extra cost. Never use rechargeable batteries because they may not always provide a consistent charge.

Carbon Monoxide Alarm Twin Pack Reviews
Great product with a great reputation. Pricing was good and very easy to install.. put on on every floor and every bedroom
Fast and as expected. Would purchase again.
Item arrived in a timely manner and in excellent packaging.
A good package that contained 2 fairly good looking meters run by 2 AA batteries included. Installation instructions were clear and the installation itself was easy two sheetrock screws each -- also included. The testing button is very large and makes testing easy, if youve mounted them on the ceiling, just use a stick to depress the test button. Although necessarily high pitched and loud, the test is short unlike my smoke detectors. All in all Id recommend these.
Very easy to install and maintain. I purchased CO alarms for the entire family - 5 households.
This Alarm brings great relief in our concern of carbon monoxide poisoning
2 Pack Carbon Monoxide Detectors
I originally purchased 9 packs of these but have only installed 4 so far, I am not seeing the false alarms as noted by some others. However it is confusing that it is rated for 5 years, but it is not clear if its from manufacture date or install date. I had to call First Alert to find out and spent over 15 mins on the phone tree, waiting and finally given a correct number to call.
Easy to Install and Test
We installed these in all the bedrooms. They were replacements for another brand that would not stop chirping no matter what we did. These are much much nicer.
